日前,由中国石油石化研究院承担完成的一种管式裂解炉蒸汽裂解制乙烯方法,获得国家发明专利授权。炼油厂碳四的主要用途是用作民用液化气,利用价值较低,如果将这部分碳四产品作为裂解装置的原料,可大大提高碳四产品的利用价值。这样既扩大了裂解装置的原料来源,又解决了碳四产品过剩和出厂困难的问题。为此,石化院科研人员开展了碳四与轻烃的共裂解研究,选择富含链烷烃的轻烃和碳四混合作为管式裂解炉蒸汽裂解制乙烯的原料,在保证轻烃的裂解性能和乙烯收率不变的情况下,有效提高碳四裂解的乙 Recently, China Petroleum and Petrochemical Research Institute to undertake a tubular cracking furnace steam cracking ethylene method, access to national invention patents. The main use of refinery carbon four is used as civilian liquefied petroleum gas, the use of low value, if this part of the four carbon products as cracker of raw materials, can greatly enhance the value of carbon four products. This not only expands the sources of raw materials cracking unit, but also to solve the carbon four product problems and factory problems. To this end, petrochemical academy researchers carried out the C4 and light hydrocarbon co-cleavage study, select the light paraffin-rich hydrocarbons and carbon four mixed as a tubular cracking furnace steam cracking of ethylene raw materials, to ensure the cracking of light hydrocarbons And the ethylene yield unchanged, effectively improve the carbon four split B
